The video shows a bus full of Suits stars — including Gabriel Macht and his wife, Jacinda Barrett — giddily riding a bus to Prince Harry and Meghan’s nuptials on May 19 and breaking out into song.

“Goin’ to the chapel and we’re gonna get married,” the group sings enthusiastically, before forgetting most of the lyrics thereafter. The voices soon start to trail off as many aren’t quite sure what the next few lines are in the song. More than a few of the passengers shift to a safer, “duh, duh duh duh duh duh, duh duh.”

A few — Abigail Spencer in particular nails the last line — manage to finish out the chorus, which ends: “Gee, I really love you, and we’re gonna get married. Goin’ to the chapel of love.”

“Well, that was amazing,” Cropper wrote on Instagram after the wedding. “Thank you Meghan and Harry for the invite to what was truly a beautiful union of love. Not too mention a historical moment in time! We love you. #royalwedding”
